Epicuticular wax of Eragrostis curvula
Phytochemistry, 1982Abstract Epicuticular wax of Eragrostis curvula contains hydrocarbons (6%), esters (13%), acids (3%), alkanols (4%), tritriacontane-12,14-dione (47%), 5(S)-5-hydroxytritriacontane-12,14-dione (14%) as major components. The esters consist of triterpenol esters (42%) as well as alkanol esters. The free alkanols consist principally Of C16C32 components,

Epicuticular wax of four species of Chionochloa
Phytochemistry, 1983Abstract Shoot epicuticular wax of four species of Chionochloa contained esters (21–38 %); alkanes (15–29%); aldehydes (4–13%); alcohols (8–16%) and acids (1–5%). The major carbon chain lengths ranged from C 24 to C 32 in the acids, alcohols and aldehydes and C 29 and/or C 31 in the alkanes.

Influence of Epicuticular Waxes on the Photolysis of Pirimicarb in the Solid Phase
Journal of Agricultural and Food Chemistry, 1998The influence of epicuticular waxes extracted from different fruits on the photodegradation of pirimicarb (I) in the solid phase was studied. Waxes were extracted with CHCl(3) and CHCl(3)/CH(3)OH from nectarines (N), oranges (O(R)), and mandarin oranges (M). All of the waxes affect the qualitative behavior of the photodegradation of I: the formation of

The ketol constituents of Brassica epicuticular waxes
Chemistry and Physics of Lipids, 1977Abstract The minor ketol constituents of the leaf epicutucular waxes from 4 Brassica species (cabbage, broccoli, cauliflower and rape) were isolated and characterised by chromatographic methods and mass spectrometry. Two classes of ketols, both of which contained two major isomers, were identified in all the waxes, a novel α-ketol fraction ...

Epicuticular wax of Pinus radiata needles
Phytochemistry, 1978Abstract Epicuticular wax isolated from the cotyledons and primary needles of 10-week-old Pinus radiata seedlings is similar in composition and contains 86% neutral compounds, viz. alkyl esters (25%, C 24 –C 64 ), nonacosan-10-ol (52%), heptacosane-5,10-diol (2%), nonacosane-4,10-diol, nonacosane-5,10-diol, and nonacosane-10,13-diol (total 12%) and

Epicuticular Wax Ultrastructure and Systematics
1994Based on scanning electron microscopy (SEM) techniques a vast amount of systematically relevant information on the structure and composition of cuticular surfaces has been accumulated (Behnke and Barthlott 1983; Juniper and Jeffree 1983; Barthlott 1990).

Epicuticular wax ultrastructure and classification of Ranunculiflorae
1995Epidermal surfaces of about 199 species from 66 genera of ranunculiflorous families are examined by scanning electron microscopy. The micromorphology of their epicuticular wax crystals is presented and discussed under taxonomic aspects. All families of the Ranunculiflorae s. str.

Seed epicuticular wax of avena sativa
Phytochemistry, 1985Abstract The main fractions in oat seed wax are β-diketones (15.5%), alkanols (14.4%), hydroxy-β-diketones (12.2%), esters (11.1%) and fatty esters (7.2%).

Effect of the Epicuticular Waxes of Fruits and Vegetables on the Photodegradation of Rotenone
Journal of Agricultural and Food Chemistry, 2004The effect of epicuticular waxes extracted from fruits (apple, nectarine, pear, and plum) and vegetables (tomato and eggplant) on the photodegradation of rotenone was studied. The waxes affected the decay rate and the degradation pathway of this botanical insecticide.

Molecular genetics of epicuticular wax biosynthesis
Trends in Plant Science, 1996The epicuticular wax (EW) layer that coats the outer surface of plants is composed of a variety of long chain length hydrocarbons. Genetic studies indicate that a very large number of genes are involved in wax production. However, the pathway(s) by which the waxes are synthesized and deposited onto the plant surface remain elusive.
